Horse breeding Horse breeding is reproduction in horses, and particularly the human-directed process of selective breeding of animals, particularly purebred horses of a given breed.Planned matings can be used to produce specifically desired characteristics in domesticated horses.he gestation period lasts for about eleven months, or about 340 days (normal average range 320–370 days). During the early days of pregnancy, the conceptus is mobile, moving about in the uterus until about day 16 when fixation occurs.

Gestation Gestation is the carrying of an embryo or fetus inside female viviparous animals. It is typical for mammals, but also occurs for some non-mammals. Mammals during pregnancy can have one or more gestations at the same time (multiple gestations). The time interval of a gestation is called the gestation period. In human obstetrics, gestational age refers to the embryonic or fetal age plus two weeks. This is approximately the duration since the woman's last menstrual period (LMP) began.

- Gestation and Birth. The gestation period for zebra reproduction takes around 12 to 13 months. Similar to horses, the foal will be able to stand up and walk just a few minutes after it is born. In fact, after only 15 minutes, the foal can walk and after one hour, it will be able to run.

- There are both anatomical and cyclical differences seen in jennets compared to mares. For the horse, the average length of gestation is 335-345 days while in donkeys it is 360-375 days or more. Normal donkey foals have reportedly been born at 10 ½ months up to 14 months of gestation. The estrous cycle of jennets ranges from 23-30 days, whereas the mare has a slightly shorter cycle of 21-25 days. Additionally, jennets usually have a heat period that averages six to nine days.

Pregnancy in Horses After about 315 days of pregnancy, the mare will start to show signs of foaling. The yellowish fluid will turn into the first milk or colostrum. The udder may drip, and the muscles around her tail head may become more relaxed. Her belly may appear to drop, as the foal positions for birth.fter about three months the foal will be developing rapidly and start to look like a small horse. After about six months, the mare may start to be visibly pregnant. Mares that have foaled before may show an expanding belly sooner than a maiden mare.

Mare (Average range 320–370 days.) Usually just one young is born; twins are rare. When a domesticated mare foals, she nurses the foal for at least four to six months before it is weaned, though mares in the wild may allow a foal to nurse for up to a year.The estrous cycle, also known as season or heat of a mare occurs roughly every 19–22 days and occurs from early spring into autumn.As the days shorten, most mares enter an anestrus period during the winter and thus do not cycle in this period. broodmare is a mare used for breeding. A horse's female parent is known as its dam. An uncastrated adult male horse is called a stallion and a castrated male is a gelding. Occasionally the term horse is used in a restrictive sense to designate only a male horse.

- 1 The closer to 300 days the foaling, the more intensive the needed care will be; 2  Foals born from mares that suffered from infectious placentitis during pregnancy may be born between days 300 and 320 and yet not show prematurity as there is an accelerated developmental rate in utero with many of these foals; 340 or 341 days are accepted as the most common foaling days, but they are not a due date, merely an average of the average. 2  Foaling days after 370 days of gestation are not uncommon and usually do not represent a problem.

The Late-Term Pregnant Mare, Foaling & Newborn Foal Care The average mare has a pregnancy of about 335 days, but normal pregnancies occasionally last over 365 days. The defining aspect of the last part of the equine pregnancy is that the fetus gains size and weight most rapidly during this time, doubling in size and weight during the last 4 to 6 weeks.he mare uses more energy – and requires more nutrition – from the last 6 weeks of pregnancy through the first 6 weeks after foaling than she does at any other time. For a mare that enters the last months of pregnancy in poor condition, it can be very difficult to feed enough to improve her condition.

Equine gestation facts and figures Equine gestation facts and figures. Equine gestation is the period from conception to birth. It averages 340 days, but may range from 320 to 370 days, with mares being known to deliver a healthy foal after 399 days. If a foal is born before 315 days, it is considered premature and if born prior to 300 days, it will usually be too young to survive. Fortunately, most pregnancies and deliveries are without any complications. When a mare fails to show heat at 18 to 22 days after service, it is often because of pregnancy. A skilled examiner can diagnose pregnancy using rectal palpation as early as 20 to 30 days into gestation, and transrectal palpation between days 40 to 50 is 95 percent accurate.
